MOLD FOR FORMING BURIAL-VAULTS.

Specification of Letters Patent.

Application filed February 15, 1908. Serial No. 416,014.

To all whom it may concern:

Be it known that I, ALoNzo O. I'IUNSAKER, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Molds for Forming Burial-Vaults, of which the following is a specification.

This invention relates to improvements in sectional molds employed in the production of burial vaults made of cement or other material impervious to water so that when one of said vaults is buried in the ground over a coffin it will exclude water therefrom.

My object is to produce a new and useful mold which may be quickly set up ready for use, or that can be taken apart so that it may be easily removed from the product, and when so removed may be stored in a small space.

In the accompanying drawings,which illustrate the invention: Figure 1 represents a perspective View of my improved vault. Fig. 2 is a plan view of the same. Fig. 3 is a cross section on line III-III of Fig. 2. Fig. 4 is a detail section on line IV of Fig. 3. Fig. 5 is a detail section on line VV of Fig. at. Fig. 6 is a horizontal section on line VI-VI of Fig. 3, of the core employed in carrying out the invention. Fig. 7 is a detail perspective View showing one end and a portion of one side of a case forming the outer portion of the mold. Fig. 8 is a broken detail perspective View of the core, with the end thereof detached.

In carrying out the invention I employ a hollow rectangular frame 1, which provides a level surface for the mold to rest upon. Said mold comprises a case 2 and a core 3,

which latter is smaller than the case so thatwhen placed therein, a rectangular space 5 will be left to receive the mortar, of which the burial vault is formed. This space is of uniform width so that the walls of the burial vault will be of the same thickness throughout. Case 2 consists of two side walls 6 and two end walls 7, which latter are removably secured to the former so that the case may be taken apart preparatory to removing the vault therefrom. Side walls 6 are, preferably, made of wood, or other stiff material, and lined with sheet-metal 8 to prevent absorption of moisture from the mortar. They are also reinforced to prevent them from bulging outward from the pressure of the mortar by a plurality of uprlght members 9 and a plurality of longitudinal members 10.

They are further reinforced by two pairs of brackets 11 which abut against the longitudinal members and are provided with openings 12 to receive screws whereby they may be secured to the floor of the shop where the burial vaults are manufactured. End walls 7 consist, preferably, of sheet-metal and are reinforced at their lower edges by outturned flanges 13 which rest upon frame 1. They are further reinforced by segmental strips of wood, or other stifi' material 14: which also afford a broad surface for a straightedge, hereinafter referred to, to slide upon and thus prevent said straight-edge from being cut or unduly worn by the narrow sheetmetal edges of the end walls 7. End walls 7 are curved at their upper ends, as is likewise the top of the core, to arch the top of the burial vault, and in order that said top may be of the same thickness as the side walls of the vault, end walls 7 extend above the top of the core, as shown in Figs. 1 and 3, a distance equal to the width of space 5. Side walls 6 have grooves 15 adjacent their ends to receive the edges 16 of the end walls 7, which are held in place by the side walls being drawn firmly into contact therewith through the mediacy of tie-rods 17 and nuts 18.

(lore 3 is, preferably, made of sheet-metal so that its sides may be sprung inwardly to facilitate its removal from the burial vault, and in order that said inward movement may not be checked by end walls 19, the latter are removable so they can be taken out, as shown in Fig. 8, preparatory to springin the sides inward. The core is prevented from bulging inward beneath the weight of the mortar by longitudinal reinforcing strips 20 secured to its sides, inturned flanges 21 which rest on base 1, and transverse reinforcing members 20 detachably secured to the longitudinal members by pins 20*. Flanges 21 are turned upward near their ends 22 and like strips 20 terminate a short distance within the core so as not to interfere with the inturned marginal flange 23, formed integral with the end walls 19 for the purpose of reinforcing the same. The lower corners of the end walls are further reinforced by L-shaped metallic members 24:, adapted to engage the undersides of the upturned port-ions 22 of flanges 21. The upturned portions 22 are also reinforced by L-shaped metallic members 25 secured to the side walls of the core. The upturned portions 22 are of suflicient length to leave a Patented Jan. 19, 1909.

space 22 between their shoulders 22* and the edges of flanges 23. This space allows the end walls 19 to be moved inward slightly, away from the ends of the burial vault so they may be readily removed from said vault when removing the core.

llieinbers 24c 25 have bolt-holes which register when the end walls are in position in the core, said bolt-holes being provided for the reception of bolts 26 whereby the lower portions of the end walls are secured to the upturned portions 22. The upper portions of the end walls are secured in place by dowel-pins 27 depending from the top of the core and adapted to enter holes 28 in the upper portions of flanges 23. I

In practice the mold is set up in the position shown in Figs. 1 and 2, preparatory to forming a burial vault. Mortar is then tamped into space 5 until the same is filled. The top of the core is next covered with mortar, which is reduced to uniform thick ness by running the straight-edge, above referred to, over the curved edges of the end walls 7. The whole is now permitted to set until the burial vault has become sufliciently hard to sustain itself when the case is removed. This is readily accomplished by taking the walls thereof apart. The vault is then inverted to gain access to the core, which can be readily taken out by first removing the transverse members 20 and the end walls19, so that the sides of the core may be sprung inward away from the sides of the burial vault.

Having thus described my invention, what I claim is:

1. A mold consisting of a case, a core removably arranged therein provided with removable end walls having inturned flanges said bottom holes for securing the flanges on the core and end walls together.

2'. A mold consisting of a case and a core, the core comprising a sheet metal body having the free ends of its longitudinal sides bent inwardly at right angles to form tiai'iges, said flanges being turned upwardly adjacent their ends and terminating a short distance within the core body, means to reinforce said ends of the flanges, end walls having 'inturned base flanges, and reinforcing members seating on said flanges of the end walls to engage 'theiunder sides of said upturned parts of the core body flanges.

' A mold consisting of a case and a core therein, said COI'GCOlfiPllSlDg a body having inturned base flanges formed with ofi'set ends, end walls formed with base flanges secured to said offset ends, fastening means to secure said base flanges and said offset ends, the base flanges being disposed so that said end walls may move inwardly with respect to said core body when said fastening means are removed.

In testimony whereof I affix my signature, in the presence of two witnesses.
